Yes, in AS 2 and AS 3 you have a local scope and global scope and that's it.
You can't create new "nested" scopes using braces or other means.
The variable declaration will be moved to the top of the function by the
compiler (I think this is called "hoisting"). So if you write:
function test(para
a method / function or a class / frame

Oops, forgot to declare the i properly.
So again:
Function doLoop1():void{
for (var i:int = 0; i < 10; i++) {
trace('1st loop: ' + i);
}
}
Function doLoop2():void{
for (var i:int = 0; i < 10; i++) {
trace('2nd loop: ' + i);
}
}
If you would like the result outside of the func

Hello, yes in AS3, but I think AS2 had the same irritating issue.
Sure you can put var i:int above.
But in many other languages (like C++, Java, Perl) you write something like
for (my $i = 0; $i < 10; $i++) {
How do you define a "code section" then?

Hello, yes in AS3, but I think AS2 had the same irritating issue.

But in many other languages (like C++, Java, Perl) you write something like
for (my $i = 0; $i < 10; $i++) {
# XXX
}
an the scope of variable is limited to the loop only.

Hello,
has anybody else noticed, that the code like:

Hello :)
Your code is in AS3 ?
In AS3 :
var i:int ; // only one
for ( i = 0; i < 10; i++)
{
trace('1st loop: ' + i);
}
for ( i = 0; i < 10; i++)
{
trace('2nd loop: ' + i);
}
The FlashPlayer 9 or 10 optimize the variables and you must implement a
variable one time in the same expr
